To aZ who/m, it may concern.'

Be it known that l, JOHN E. MATTHEWS, a citizen of the United States, residing at Fremontj in the county of Dodge and State of lebraska, have invented certain new and useful Improvements in Bearing Clamps and File Guides, of which the following is a specification7 reference being had to the accompanying drawings. v

yThis invention relates to certain improvements in bearing clamps and file guides and it is primarily an object of the invention to provide a mechanism of this general character especially designed and adapted' for use inthe filing and finishing of bearings for motors, automobiles and the like.

It is also an object of the invention to provide a device of this general character having novel and improved means whereby the bearing to be filed or finished may be effectively held in desired position to be properly engaged with a iile and wherein bearings of different sizes or irregular bearings may be held by the same device.

Another object of the invention is to provide a novel and improved mechanism of this general character including a gauge for controlling the action of the file upon the bearing in accordance with the requirements of practice.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved bcaring clamp and file guide whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

fn order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings7 wherein Figure l is a view partly in elevation and partly in section illustrating a bearing clamp and file holder constructed in accordance with an embodiment of my invention;

Figure 2 is a fragmentary view in top plan of the structure illustrated in Fig ure l;

`Figure 3 is an enlarged view partly in section and partly in elevation, the line of Serial N0. 812,531.

ment of the sleeve or barrel.

As disclosed in the accompanying drawings7 B denotes a base of desired dimensions and which is adapted to be secured to a suitable support by the screws l or otherwise as may be preferred. Extending upwardly from the base B is a pedestal or standard 2 provided at its upper end with a table 3 with one side marginal portion of the table 3 and the upper portion of the pedestal or. standard 2 having associated therewith a bracing plate or web 4.

The upper surface or face of the table or platform 3 is provided withan open groove or channel 5 in which is engaged the slide G. The slide 6 is held within the groove or channel 5 by the plates 7 par-l tially overlying the `adjacent portions. of the groove or channelv 5.

The outer end of the slide 6 is provided with a depending arm 8 through which is threaded a bolt 9, said bolt being in swiveled engagement as at l0 with the table or platform 3. By requisite rotation of the bolt 9, the sliee 6 may be moved inwardly or outwardly with respect to the groove or channel 5 as the occasions of practice may require.

Extending upwardly from the slide 6 is a post l1 having its upper portion reduced as at l2 and which is adapted to 'snugly fit within an opening of a bearing A of the general type employed in connection with motors7 automobiles and the like.

v@spaced from the post ll. is a second post .le extending upwardly from the table or iilatform 3 and which also has its upper portion l5 reduced to be snugly received within the second openingr of the bearing n. By this means the bearing A is effectively maintained inv applied position through the instrumentalityl of the posts 1l. and 14. The adjustment of the plate 6 permits the post ll to bey shifted in accordance with the size of the bearing A or in the event such bearing should be of an ico irregular type. Extending upwardly from the marginal portion of the table' or platform 3 is a pair Vof spaced arms 16 with whichV are hingedly connected by the pins 17 or the like to the extremities of an elongated yoke 18. The central portion of the base or intermediate part 19 of the yoke 18 is provided with an outstanding arm 2O to provide means whereby a requisite swinging movement may be given to the yoke 18. Y

The yoke 18 is of a length to straddle both of the posts 11 and 1A and to extend beyond an applied bearing A. The intermediate portions of the side arms of the yoke 18 are connected by a cross member 21 substantially semi-circular in cross sertion and which extends within the bearing A, as illustrated in Figures 1 and 3, and when the yoke 18 is swung downwardly relatively to the bearing A it effectively clamps the bearing A in applied position upon the posts 11 and 1A. With the yoke 18'in clamping position it is to be noted that the upper marginal portions thereof and also of the cross member 21 te minato below the upper face of the bearing A so that. no hindrance or obstruction will be offered to the filing of such face.

Extending Voutwardly from the plate or web A is a lbracket 22 with which is pivotally engaged a lever 23. Secured to the lever 23 at a point 24; eccentric to the pivotal connection 25 between the lever 23 and the bracket 22 is an extremity of a retractible member 26. The opposite end portion' of the member 26 is extended to provide a hook member 27 which engages over the arm 20.

lith the hook member 27 engaged with the arm 20, the downward swinging movement of the lever 23, as is particularly illustrated in Figure 1 will result in the cross member 21 being 'effectively held in clamping action upon the bearing A. then it is desired to remove the bearing A it is only necessary to swing the lever 23 upwardly whereupon the hook member 27 can be readily disengaged from the arm 20. l v

Vith the bearing A in clamped position upon the table or platform 3 the surface of the bearing is adapted to be worked by a file or the like to properly finish or smooth said surface of the bearing` or more particularly theends thereof or to file down said. surface of the bearing tothe depth or size desired by the operator. Y Extending upwardly from the platform or table 3 at the rear portion thereof or at a point substantially directly above the pedestal or standard 2 is an enlongated post 28' with which is adapted to be freely engaged an'elongated sleeve or barrel 29. Carried by and extending outwardly from the sleeve or barrel 29 is an enlarged head 307 which when the sleeve 29 is in applied position is adapted to overlie the table or standard 3. The forward longitudinal poi ion ofthe head 30 is provided with a notch o recess 31 to receive. the upper portion 32 of the post 33 carried by the platform or table Y The pora pair of parallel rods 311 which have their upper end portions connected bythe cross members 35, said members 35 extending below the rods 311. Secured to and underlyingthe lower faces or edges of the members 3-1 are the loop members 36 through which are adapted to be directed the opposite end portions of a file F. Threaded from. above through one of the cross members 35 is a holdin@ screw 37V which is adapted to have direct contact with an end portion of the file F7 is particularly illustratedin Figure 1, to maintain the file F in applied or working position. The rods 3&1 'together with the head 30 permit the file F to be reciprocated in a liXed path of travel so that the `file F will have requisite contact with the bearing A to properly treat the surface thereof either to smooth said surface or to cut down the bearing as may be preferred.

When `applying the bearing A it is to be understood that the head 30 together with the parts carried thereby is first swung into an inoperative position and thatthe yoke 18 is also swung upwardly out of the way.

also find it of advantage to provide means to positively limit the downward movement of the sleeve or barrel 28 whereby to regulate or control the action of the lile F upon the bearing A. As herein disclosed l provide a vertically disposed arm 38 which overlies the rear face of thepedestal or standard 2 and terminates at its upper end Vin a forwardly directed plate 39 through which the rod 28 is disposed. said plate 39 being capable of freely moving lengthwise of the rod 23. The opposite or lower end portion of the arm'38 is provided with aV longitudinally disposed slot Ll-O through which is directed a clamping screw 4:1, said screw having threaded engagement with the pedestal or standard 2 as is clearly illustrated in Figure 3.

Extending laterally of the side marginal portion of the arm 38 and herein disclosed as at a point above the slot 10 is a pointer. or index 42 which ccacts with the graduations 4 3 suitably produced on the rear face of the pedestal or standard 2 whereby the vertical ad'iwtnient of the arm 38 may be readily and which is of particular importance when the bearing A is being filed down.

The plate 39 carried by the upper end portion of the arm 38 underlies the bearing A so that the downward movement of said sleeve or barrel 29 is positively limited, such limitations also controlling the extent of downward movement of the file F with respect to the bearing A.

From the foregoing description' it is thought to be obvious that a bearing clamlp and file guide constructed in accordance with my invention is particularly well adapted for use b-y reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason l do not wish to be understood as limiting myself to the precise arrangement yand formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
